I sent an e-mail a week ago to Holbren looking to order a head for my 6'' jointer. He still hasn't responded. I ordered 70 inserts and screws from Holbren on 3/27/17. I followed up on 4/5 and got the first shipment on 4/8. It was short 30 screws, so they had to drop ship more, which ended up coming in 4/12/17. He did finally take care of the order, soI was willing to give it another shot. After a week of no response, I finally placed my order from Grizzly. I've heard lots of great reviews from others on this board dealing with Holbren; I just wish my experience was similar.
I ordered a head for my 6" jointer and was told 6-8 weeks for delivery. It just happened to ship today, one day past 7 weeks.
